Comments about Kendrick Kendrick Dew Remover Heater for Telrad Sight Finder:

I love the Telrad. Best easy to use viewfinder for large dobs. No more headaches trying to find stars in traditional little peep hole viewfinders. Only one drawback - too easy to accidently turn on given the side location of the on/off switch. I put mine into my box of astronomy goodies and the switch came on accidently at full power. It fried the diode or whatever it is that projects light by the time I discovered it was on.
